I use a lot of single-action lists as well, but really other than the icon (which is a very nice visual distinction), I've been at somewhat of a loss to understand the real difference between a single-action "bucket" list and a project set to parallel actions.

Perhaps somebody can enlighten me as to what the advanced distinctions are, but I seem to recall these buckets simply as a holdover from the early days of OF when all "Projects" were sequential and there simply was no "parallel" choice for projects.
